Abstract

L'invention concerne la protection contre la corrosion de l'appareillage utilisé pour le traitement des polymères halogénés. Elle se rapporte à un procédé qui comprend la disposition d'une anode au voisinage des surfaces métalliques qui peuvent être corrodées par le polymère halogéné, l'anode étant formée d'un métal dont le potentiel normal d'électrode est supérieur à celui de la surface à protéger. Application à la protection de l'appareillage utilisé pour le traitement du caoutchouc halogéné.
